Reissuedz Sept. 9, 1930 t UNITED STATES PATENT oI-fFIcE DANIL HANDELAN, OF MINNEAPOLIS, MINNESOTA HUMIDIFYING DEVICE original No. 1,665,455, dared April 1o, 192s, serial No. 32,936. filed May 2c', 1925. ',aenewed February 12,

- 1927. Application for reissue filed January 29, 1930.l Serial invention relates to humidifying devicesand has' for an object the provision of Va device which will maintain the air in rooms' of buildingsl in a kmoistened condition. An-

other object is the provision of a device which will purify the' air in rooms.

The full objects and advantages of my invention will appear in connection with the .detailed description thereof, and the novel feature of my inventive idea will be particularly pointed out in the'claims.

In the accompanying drawings, lwhich illustrate a practical embodiment of my in- Fig. 1 is an elevational view showing the device set into the wall of a building. Fig. f 2 is aV view ofthe device in substantially central vertical section. Fig. 3 is a'fragmentary view'l in vertical section on the line 2o 3-3 of Fig. 1. Fig. 4'is a fragmentary view corresponding to Fig. 3'but showing a slight modification. Fig. 5 is a view in horizontal section on the line 5-5 of Fig 1 and on 'an ,enlarged scale. Fig. 6 is a front elevational view of a register casing with a small portion i broken away.`

view of a register cords stretched between portions thereof.

-Referring to the construction shown in the drawings two studs of a building are indicated at J and J. The casing 10 which is included in my' device is set into the space between these two studsbefore the laths L and the plaster P are applied. The bottom of the casing 10 is positioned near .the iioor F of the room and its top is located toward the upper portion ofthe room. A drain pipe 12 leads from the bottom of the casing and a water supply pipe 14 leads. into the top of the casing. The pipe 14 is provided with a cock 16 by which the supply ofwater may be regulated and entirely shut oii' when de` sired. The inner end of pipe 14 terminates in the upper portion of the casing 10 at substantially the middle of this portion and is turned downwardly and provided with a lspray nozzle 18. This nozzle is preferably `of brass and has a tiny hole about the size of a pin through which thewater is forced frame member showing the side and end Fig. 7 is a rear elevationalv by the city water pressure. The casing is closed'eXcept for a lateral register opening at the upper end; thereof anda lateral register opening somewhat above the bottom. The register openings are providedrwithsimilar registers one of which will be described injdetail. The register includes a registercasing shown in Fig. 6 whichis in the form of ay frame having its front provided with inwardly-turned iianges 20 and 22 at the sides andan upwardly-turned fiange 24 at the bottom. The register casing on the rear is provided with flanges 26 which are secured in suitable manner, as by soldering them to the material of the casing 10 around the register opening therein. The register'- fr ame shown in Fig. 7 is in the nature of a slide adapted to be slid between the fianges 20 and 22 of theregisterl casing. This frame on its rear has the' outer margin turned inwardly at the sides to form the flanges 28 and 30 and turned upwardly at the bottom to form the flange 32. The upper margin of this sliding frame is provided with a flange 33 at the rear and with a flange 34 at the front, which, when the frame is in place in the casing, matches with the anges 2() and 22 andcompletes the ornamental appearance of the device. The inner margin of the frame is provided at the rear with a surrounding inwardly-directed ange 36 provided with equally spaced cuts 38, asshown in Fig. 7, around and through which a cord 40 or other flexible material is strung. This flexible material may be strung back and forth horizontally and vertically and also in inclined direction to give the center of the register the grilled-'appearance shown in the drawings. The lower flange ofrthe lower register casing may be extended and deflected outwardly if desired, as indicated at 24 in Fig. 4, in order to catch any'moisture which runs down the Vcord 40. The lower portion of the casing 10 is provided with a hood-like partition 42 which at its upper end curves out- `wardly from. the top of the lower register opening and then extends downwardly with-4 in the middle of the casing and stops somewhat short of the bottom ofthe latter, said partition forming a bend in the passageway within the case at a point between the two registers and constricting said passageway nozzle 18 in the form of a fine mist. The

downward movement of this spray causes impure air in the room to be drawn in through the upper register, which, as will be understood, is located toward the topof the room. During its downward passage through the casing 10 the air thus drawn in is mixed with' atomlzedy water, which humidifies it andl washes out impurities. The impurities are carri-cd oil' by the water which collects in the Y bottom of the casing and escapes through the drain pipe 12. Theypurilied and humidiied air is delivered back into the room throu h the lower register. Y The provision. of t e partition 42 causes any drops of water which may coalesce to gravitate to the bottom of the casing so thatA they will not pass out through the register. kWhen the'device is located in the wall of the room in the manner shown it is out of the way with only the 4 registers exposed, and since these 'are of ornamental appearance, the installation of theI device does not detract from the appearance of the room. The form of register which I have adopted for use in connection with this humidifying device-is particularly adapted for use therewith. The register frame may be slid upwardly out of the register casing when it '1s desiredto expose the interior of the Hue-like casing 1 0. The provision of the' register frame havingthe rear surrounding flange 36 with equally spaced cuts 38 renders it an easy 4matter to string the flexible elements 40 back and forth in such manner as to present a pleasing appearance and the string, ing may be readily renewed when desired.
